Steel: 6140CrV 44-48 HRC Nickel plating A: 23 mm; B: 16 mm; C1: 5 mm; C2: 8 mm; Length: 150 mm The classic version of a combination wrench with a socket profile on one side and a twelve-sided hexagonal profile on the other. The combination wrench is the most common type of wrench as it combines the capabilities of a socket and a hexagonal profile. The hexagonal profile is offset from the longitudinal axis of the wrench by 15 degrees, allowing for work in limited spaces. The precision manufacturing of the twelve-sided hexagonal profile minimizes the likelihood of the fastener edges stripping. The inclination angle of the socket part relative to the longitudinal axis of the wrench is 15 degrees, allowing for a minimal angular step of 30 degrees when working in hard-to-reach areas. You can also purchase combined wrench sets.
